5.长期议题（2012）：农民的选择与生物燃料的未来
[农、林、牧、渔业,电力、热力、燃气及水生产和供应业] [2014-03-26]
This paper focuses on the patterns of farmers choices regarding dedicated perennial lignocellulosic energy crops. Throughout this paper we use the term perennial as shorthand for warm season grasses such as those in the genus Panicum or Miscanthus, or short rotation tree crops such as those in the genus Populus or Salix. We focus on choices about these perennial crops because two thirds of the mandated advanced biofuels are expected to be converted at biorefineries from perennials (USDA 2010). RFS2 establishes the goals, but not mechanisms for achieving them. Mechanisms and incentives, however, are embedded in other legislation and programs.

6.密西根湖鲟的修复策略
[水利、环境和公共设施管理业,农、林、牧、渔业] [2014-02-22]
Substantial population declines since the 1800s led the State of Michigan to list lake sturgeon as a threatened species. The primary causes of the decline of lake sturgeon are insufficient recruitment due to habitat loss and degradation, often caused by dams and poor spawning habitat quality, and excess mortality on adults through fishing. This document provides guidance for the management of lake sturgeon with the goal of eventually rehabilitating this species to the point of removal from the threatened species list and to levels that provide productive and unique fishery opportunities. The primary goals for lake sturgeon are to: (1) conserve populations that are currently self-sustaining; and (2) rehabilitate depressed populations to the point that they are self-sustaining at a higher level of abundance. Currently, there are 24 lake sturgeon populations as distinguished by major watersheds in Michigan waters: two in the Lake Superior drainage, 11 in the Lake Michigan drainage, nine in the Lake Huron drainage, and two in the Lake Erie/Lake St. Clair complex. Of these 24 populations, only five are large in size and three of these are considered to be abundant and stable enough to support harvest fisheries. Among the remaining 19 populations, 12 are below the minimum viable population size (80 adults) and are at high risk of extirpation due to random factors. Four populations are classified as small in size (80200 adults) and are at a high risk of declining to below the minimum viable population size. Three populations are classified as medium in size (200750 adults).

7.使用鱼传感器对俄勒冈州福斯特大坝穿过鱼梁和一号机组鱼通道条件的描述，2012.
[农、林、牧、渔业] [2013-12-28]
Fish passage conditions through a Kaplan turbine and spillway fish weir at Foster Dam, located on the South Santiam River in Linn County, Oregon, were evaluated by Pacific Northwest National Laboratory for the U.S. Army Corps of Engineers, Portland District, using Sensor Fish devices. The objective of the study was to describe and compare passage exposure conditions, identifying potential fish injury regions encountered during passage via specific routes. The investigation was performed in May 2012, concurrent with HI-Z balloon-tag studies by Normandeau Associates, Inc. Sensor Fish data were analyzed to characterize the passage exposure conditions through the spillway fish weir and turbine Unit 1 at Foster Dam at two forebay pool elevations (616 and 634 ft mean sea level (MSL)) and to estimate data relationships with live fish injury and mortality estimates. For the spillway fish weir evaluation, Sensor Fish and live fish were deployed through injection system piping mounted on the weir. The bottom of the injection pipe was at an elevation of approximately 614 ft during testing at the 616-ft MSL (low) forebay elevation and at 632 ft during the 634-ft MSL (high) forebay level tests. Two systems were useda 4-in. pipe for juvenile fish releases and an 8-in. pipe for adult releases at each elevation.

8.具有毒性共同机制的农药化学品的累计风险评估的指导
[化学原料和化学制品制造业,农、林、牧、渔业] [2013-11-28]
In assessing the potential health risks associated with exposure to pesticides, attention has historically focused on single pathways of exposure (e.g., from pesticide residues in food, water, or residential/nonoccupational uses) for individual chemicals, and not on the potential for individuals to be exposed to multiple pesticides by all pathways concurrently. In 1996, the Food Quality Protection Act (FQPA) imposed upon the Office of Pesticide Programs (OPP) the requirement to consider potential human health risks from all pathways of dietary and nondietary exposures to more than one pesticide acting through a common mechanism of toxicity. This document provides guidance to OPP scientists for evaluating and estimating the potential human risks associated with such multichemical and multipathway exposures to pesticides. This process is referred to as cumulative risk assessment.

9.加州粮食和农业部门合同协议号98-0241的最终报告。加州杀虫剂的使用报告的数据质量。
[农、林、牧、渔业,化学原料和化学制品制造业] [2013-11-28]
The California Department of Pesticide Regulation's (DPR's) Pesticide Use Report (PUR) is probably the largest and most complete database on pesticide use in the world. A system to collect information on pesticide use in California has been in operation in some form for over 50 years, with the current use reporting system started in 1990. The PUR contains information on nearly all production agricultural pesticide use and some nonagricultural use in California. The data collected include the pesticide product used, the date it was applied, the particular field treated, and application location to a square-mile section. Production agricultural use includes applications to growing crops, agricultural fields, and most applications to forest trees and ornamental turf. Other pesticide uses reported to DPR include post-harvest commodity treatments, right of way, landscapes, structural use, and other nonagricultural uses by commercial applicators. Because of the importance of the PUR for many groups and individuals, it is critical that the database be an accurate and complete as possible.

10.农业化学物质：美国农业部可以提高农药和化肥的使用数据，提高推广，更好地利用资源
[农、林、牧、渔业,化学原料和化学制品制造业] [2013-11-28]
The use of pesticides and fertilizers contributes to U.S. agricultural productivity and helps ensure a generally stable, plentiful, and inexpensive food supply. However, these chemicals may also harm human health, water quality, and food safety. The U.S. Department of Agriculture's (USDA) National Agricultural Statistics Service (NASS) collects, analyzes, and disseminates Agricultural Chemical Usage (ACU) data to meet regulatory, business, and other informational needs. In fiscal years 2007 through 2009, NASS substantially scaled back the ACU program before restoring it in 2010. GAO was asked to examine (1) what factors NASS considered in reducing the ACU program; (2) how ACU data users were affected by the temporary cutback, and their views on the data's quality and usefulness; and (3) the extent to which agricultural pesticide and fertilizer usage data are available from sources other than NASS. GAO reviewed relevant NASS documents and interviewed NASS officials as well as 25 selected ACU data users.
